Configure
6.

Educate the technical team
Get to know your system administrator and DBA
Changing settings, can easily break SharePoint
Generally not even be SharePoint specific, think database, office, security, internet explorer

Configure the right way
Always use SharePoint UI’s for changing settings e.g. central administration not IIS
Consider the database as off limits until you have read the necessary white papers from Microsoft.
IT and the business need to work together on settings changes

9.
Demo

Minimize the risk
Ensure test strategy is defined
This needs to involve the key stakeholders and key business functions
Push changes through the test environment first

Repeatable Process
Avoid “This problem only happens on production”
Document
Script
Use a tool to synchronise

Customise
12.

Common types of customisation
Web parts
Content Types
Branding
Workflow
These are not as harmless as they sound

Web parts
Content Queries – Large queries
XSLT – Incorrect syntax
RSS – Malicious feeds, internet access
Page Viewer – Malicious content
Consider what web parts are appropriate

Content types
Changes may not propagate as expected
Adding fields work well
Fields with the same display name
Fields with different internal names in locations

Branding
Rapid development is possible using tools like SharePoint designer
Changes may break the entire site
Think about different sorts of sites
Meeting workspaces
Search
Back-up and rollback strategy
Move between system environments

Workflow
How will this be tested
Loops, annoying test emails, deleting information
Deployment strategy

18.
Demo

Solution
Control using security and policy but need to preserve the goal
Educate the users
Provide a training playpen
Customisations should go via a test server too
Monitor the system
Have a backup and rollback strategy

Code

Code
Why are you writing code ?
Negotiate first, code second
Code sources:
Buy
Download
Develop
Do you have a support strategy ?

Develop the right way
SharePoint code is just .Net code but has it’s own best practises
Traps for new players
Memory management
Excessive database round tripping
Forgetting about scale
Forgetting about security

Common symptoms of memory leaks
Frequent recycles of application pool, especially during peak usage
Application crashes that appear as heap corruption in the debugger
High memory use for Microsoft Internet Information Services (IIS) worker processes
Poor system and application performance

Getting memory right is hard
using(SPSite site = new SPSite("http://server")){
using(SPWeb web = site.OpenWeb()){...}}
using( SPWeb web = SPControl.GetContextWeb(HttpContext.Current)) { ... }
using (SPWeb web = new SPSite(SPContext.Current.Web.Url).OpenWeb()) { ...}
But SPDispose check helps

Testing conditions
Does will it work with the following:
Large number of sites and lists
2000+ items in a folder
Multiple web servers
Alternative access mappings
Does it work for different users
Reader
Contributor

Package
Create features and bundle into solution (WSP) to deploy
WSP’s automatically get deployed to all servers in the farm
WSP’s can do more than just deploy web parts and files
Staple your features if needed on site creation
